LINKAGE.

Application filed March 18, 1925. Serial No. 16,531.

This invention relates generally to linkage and refers more particularly to toggle link age.

One of the essential objectsof the invention is to provide a linkage of this type in which the pivotally connected sections of two toggle links are preferably connected together attheir outer ends and are preferably spaced apart at their inner ends by a resilient member which preferably extends between the pivotal points of the toggle links.

Another object is to provide a simple and reliable system in which the sections of each toggle link normally extend at an angle to each other and areadapted to be subjected at their outer endsto a force tending to align the sections.

A further object is to provide a construction of the type described in which the force applied at the outer ends of the toggle link sections may be resisted by a very hght spring which is preferably applied at the pivotal points of the toggle links.

Still another object is to provide a simple construction'that can be manufa-ictnred at a comparatively low cost.

F igure 16 is an enlarged side elevation of the linkage and scale construction shown in Figure 15.

Referring now to the drawings in which like characters of reference designate corresponding parts throughout the several views, the numeral 1 designates a linkage embodying my invention. As shown, this construction preferably consists of two toggle links 2 and 3 respectively which are pivot-ally con nected at their outer ends as shown at l and 5 respectively. Any suitable means, (not shown) may be applied to the outer pivots land 5 respectively for exerting a force tending to align the toggle links. In order that the force applied to the outer ends of the links may be resisted and gradually and effectively cushioned, 1 preferably provide a suitable coil spring 6 that is preferably positioned between the pivots 7 of the toggle links 2 and 3 respectively. As shown in Figure 2, this spring is preferably provided at its opposite ends with suitable curved arms 8 that are secured to the pivots 7 of the toggle links. Thus, the toggle links will normally be held at an angle to each other by the tension of the spring 6. Inasmuch asthis spring is located between the intermediate pivots 7 of the toggle links, it is readily apparent that the resistance of the spring increases when the toggle links straighten out consequently light springs will suliice. Moreover the construction is such that a terrific force may be applied to the outer ends of the toggle links without materially affecting the springs (i.

In Figure 3 I have shown a slight modification in which the upper section 10 of each toggle link 11 and 13 respectively is provided with elongated slots 11 for receiving the pivots 15. y

In Figure 4 I have shown still another modification in which the adjacent end portions 16 and 17 respectively of the toggle sections 18 and 19 respectively are preferably otf-set slightly at an angle and receive the curved end portions 20 of the coil spring 21 therebctween.

In Figures 5 and 6 another modification is shown wherein the sections 22 and 23 respectively, .of. each toggle link are preferably spaced slligl tly apartr and are connected at their adjacent ends by parallel linlgs 2 h this c ns ructi etlle ar endemiand riyeted head thereof.

In Figure 1O.I;l1ave shown another modifi cation in which the sections 53 of the linkage 54k are preferably formed of cables which may be formed ofany suitable material such steel, These cables may be secured at their inner ends by anysuitable means to the parallel links 5% and may be connected together by any suitable means at theirv outer ends for the purposes set liorth in connecitionwith the devices shown in the preceding figures.

The adaptr Plate m ytake any f m desir d b i p 'ei'erabflypro ided with a centraillytlireaded opening that receives the usual. ex- ,teriorly threaded wheel hub 66 and has three depending apertured lugs 67, 68 and 69 re- ;sreetirela hnerder that y movement of the vehicle in opposite directions may be aken care of by my anchorage i l ri e, th ver plates :63 a e; p eferab y lecatedzin, advance and in rear oi each wheel of the; ehicle and are p et rahly cu e to the. oeriof the he gh by mc n in t'i suitable nails 70,, To facilitate attachmentot the tiemeinbersbe, these floor plates 6;} are, preferably preyided; intermediate their ends wit upstan i g; gs 7 l, which mm prefera ly pac l uii cient y apet ie waive the lower ends. oi the tiernernbens 64.

Furthermore, a ditferent form of inter 12g:

mediate tie member may beusedin conneo tion with the tie members 64. As sheWHinH .FigurejQ, I preferably useithez tie member 9O that consists t he se t ons .9lwando92i respectively which are conneeted at; their as i adjacent ends by parallel links 93. As shown, the section 91 is preferably pivotally connected at its lower end to the spaced up standing lugs 94 of the floor plate 95, while the section 92 is preferably loosely connected by the link 96 at its upper end to the centre depending lug 68 of the adapter plate 62. The sections 91 and 92 of this tie member are also slotted as shown at 97 to receive the pivot elements 98 connecting the same to the links 93. Thus, this tie member will also compensate for flat tires and in fact will give more freedom than the links 96 alone.

In Figures 13 and 14 I have shown my linkage construction used in connection with a supporting device for a passenger car 100 of a mono-rail system. As shown, the. upper sections 101 of the toggle links are pivotally connected to a. suitable hanger 102 extending downwardly from the monorail, while the lower sections 10;} of the toggle links are preferably pivotally connected to a suitable bracket 10% secured to the passenger car preferably at the bottom thereo't'. Thus, the linkage construction will effectively cushion the passenger car while in suspension.

In Figures 15 and 16 I have shown my linkage construction in connection with a suitable scale and hoist. As shown, the upper sections 105 of the toggle links are pivotally connected by a suitable bolt 106 which is adapted to be engaged by a. suitable hook 107 at the free end of a suitable cable 108.

The scale is designated generally by the numeral 111. As shown, the upper sections 105 of the toggle links are pivotally connected to a vertical rod 113 which in turn is preferably connected to the bolt 106. The lower sections 114 of the toggle links are preferably pivotally connected at their lower ends to a. vertical rod 115 which is adapted to actuate the mechanism designated generally by the numeral 116 of the scale 111. Any suitable means such as the hook 117 may be attached to the pivot 118 at the lower ends of the toggle linl' for supporting the articles while being weighed.

lVhile it is believed that from the foregoing description the nature and advantages of the invention will be readily apparent. I desire to have it understood that I do not limit myself to what is herein shown and described, and that such changes may be resorted to when desired as fall within the scope of what is claimed.

What I claim as my invention is:

1. A linkage comprising two toggle levers having toggle pivots spaced laterally apart, and having the opposite end portions of said levers arranged in overlapping relation, pivot elements extending through said overlapping end portions, and means for resisting movement of said toggle pivots toward each other, including yieldable means extending between said toggle pivots and terminally secured thereto.

:2. A linkage comprising two toggle levers having toggle pivots spaced laterally apart and having the opposite end portions 01 said levers arranged in overlapping relation, pivot elements extending through said overlapping end portions and constituting attaching means for said lin (age, and means for resisting movement of said toggle pivots toward each other, including a coil spring extending between and terminally connected to said toggle pivots.

A hold-down for vehicles and the like coinprising an adapter plate attachable to a part of a vehicle, an anchorage plate attachable to a floor or support for the vehicle, and an intermediate tie member comprising two toggle levers having the opposite end portions thereof arranged in overlapping relation, pivot elements extending through said overlapping end portions and pivotally connected to said adapter plate and anchorage plate, and means for resisting movement of said toggle pivots toward each other, including yieldable means extending between said toggle pivots.
